aliases and aliases.db are in /home/rbell/sendmail

Most of my messages to addressees other than myself rely on this alias
file for expansion. Messages addressed to myself that stay in the
queue
forever, complaining of an unavailable alias database, have an X-
authentication-warning
that they use my custom sendmail.cf, so sendmail should look for this
same
alias database as all my other messages.
